[. . . ] Please be advised that units in production after March 2000 will NOT have this problem. Find where the Orange & Green Wires are soldered to eyelets, pretty well in the center of the board (marked with an Orange & Green X on the layout provided). CUT the Orange & Green Wires as close to the EYELETS as possible (on the filter capacitor side). Solder both wires (that you've just cut) to TAB 3 (as shown circled in GREEN) 4. [. . . ]
